Description

Drug injection device that induces skin twisting

[0001] The present invention relates to a drug injection device that induces skin twisting.

[0002] The skin is composed of the epidermis, dermis, and subcutaneous fat layer. The epidermis prevents the invasion of pathogens such as bacteria and blocks the loss of body moisture. The dermis is located beneath the epidermis and contains collagen, elastic fibers, and matrix; it plays a role in skin elasticity, radiance, and firmness. Additionally, the subcutaneous fat layer is located below the dermis and functions to absorb external pressure or shock and maintain body temperature.

[0003] As skin ages, it is inevitable that it gradually loses elasticity and develops wrinkles. This is generally because the amount of collagen, elastic fibers, and matrix in the dermis decreases, as does the amount of moisture.

[0004] To solve this problem, a needle tip has been developed that stimulates the tissues forming the skin by inserting multiple needles into the skin, while simultaneously outputting thermal energy such as radio frequency (RF) to induce coagulative necrosis of the skin, thereby regenerating and activating the skin's collagen and elastic fibers.

[0005] However, conventional needle tips had a problem in that they only applied high frequency to the skin, so the intercellular connection signals of the skin could not be stimulated.

[0006] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a drug injection device that induces skin twisting, thereby enabling a drug applied to or sprayed onto the skin surface to be efficiently injected along an injection hole formed in the skin by inducing twisting on a target area of ​​the skin.

[0007] The problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art from the description below.

[0008] A drug injection device for inducing skin twisting according to one embodiment of the present invention comprises: a plurality of needle holders; a plurality of needles each fixed to a plurality of needle holders and inserted into a target area of ​​the skin to form an injection hole; and a driving device for selectively rotating each of the plurality of needle holders, wherein a drug applied to the surface of the skin or a drug sprayed onto the surface of the skin is injected into the injection hole.

[0009] Additionally, a plurality of needle holders includes a first holder group comprising one or more of the needle holders and a second holder group comprising one or more of the needle holders, and the actuator can rotate the first holder group and the second holder group in different directions.

[0010] In addition, the actuator can selectively rotate one or more of the plurality of needle holders.

[0011] In addition, a plurality of the above needle holders can be arranged in a concentric circle shape.

[0012] In addition, the needle holder located in the center among the plurality of needle holders may have a circular shape, and the remainder among the plurality of needle holders may have a ring shape.

[0013] In addition, the ring-shaped needle holder may be positioned to surround the circular-shaped needle holder.

[0014] In addition, the above actuator can rotate the circular needle holder at the slowest speed.

[0015] In addition, the above actuator can rotate the ring-shaped needle holder at a gradually faster speed as it moves further away from the center.

[0016] In addition, a plurality of the above needles can be fixed at intervals along the rotational direction of the needle holder.

[0017] In addition, a gap may be formed between two adjacent needle holders.

[0018] In addition, the actuator may include at least one of an electric motor, a pneumatic motor, a hydraulic motor, and a magnetic motor.

[0019] In addition, it may further include a pressure regulating part that forms negative or positive pressure in the pressure acting space of the cylinder.

[0020] In addition, it may further include a feedback sensor that automatically controls the rotational speed of the above actuator.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0035] FIG. 1 is a perspective view showing a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention, FIG. 2 is a cross-sectional view showing a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention, FIG. 3 is another perspective view showing a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention, and FIG. 4 is another cross-sectional view showing a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention.

[0036] As illustrated in FIGS. 1 to 4, a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention includes a plurality of needle holders (10), a plurality of needles (20), and an actuator (30).

[0037]

[0038] *Multiple needle holders (10) can each serve to fix multiple needles (20).

[0039] A plurality of needles (20) are each fixed to a plurality of needle holders (10) and inserted into a target area of ​​the skin (1) to form an injection hole in the skin (1).

[0040] For example, a plurality of needles (20) may be fixed at least one per plurality of needle holders (10). Here, the plurality of needles (20) may be fixed at intervals along the rotational direction of the needle holders (10).

[0041] As another example, a drug applied to the surface of the skin (1) or a drug sprayed onto the surface of the skin (1) may be injected into the injection hole formed in the skin (1). Here, the drug applied to the surface of the skin (1) may have been applied to the surface of the skin (1) in advance through a drug applicator (not shown) installed in the needle holder (10). Additionally, the drug sprayed onto the surface of the skin (1) may have been sprayed onto the surface of the skin (1) through a drug applicator (not shown) installed in the needle holder (10).

[0042] The actuator (30) can selectively rotate each of the multiple needle holders (10). Here, the direction in which the actuator (30) rotates the needle holder (10) may be a first direction or a second direction. At this time, the first direction may be defined as either a clockwise or a counterclockwise direction, and the second direction may be defined as either a clockwise or a counterclockwise direction. The actuator (30) may include at least one of an electric motor, a pneumatic motor, a hydraulic motor, and a magnetic motor. The rotational speed of the actuator may be automatically controlled by a feedback sensor. The feedback sensor may automatically control the rotational speed of the actuator. Here, the feedback sensor detects the rotational speed of the actuator's drive shaft in real time and compares it with a set speed; if it is overspeed or underspeed, the actuator is controlled to maintain the rotational speed of the drive shaft at the set speed. The feedback sensor may include at least one of an optical encoder, a Hall sensor, and a current sensor. A plurality of needle holders (10) may include a first holder group comprising one or more needle holders (10) and a second holder group comprising one or more needle holders (10). For example, the first holder group may include a needle holder (10) located in the center among the plurality of needle holders (10), and the second holder group may include a needle holder (10) located on the outer circumference of the center among the plurality of needle holders (10). Additionally, the first holder group may include a needle holder (10) located in the center and some of the needle holders (10) located on the outer circumference of the center among the plurality of needle holders (10), and the second holder group may include the remaining needle holders (10) located on the outer circumference of the center. For reference, the center can be defined as the exact center of the plurality of needle holders (10), and the outer circumference of the center can be defined as the outer circumference of the exact center of the plurality of needle holders (10).

[0043] The actuator (30) can rotate the first holder group and the second holder group in different directions. At this time, the first holder group may include a needle holder (10) located in the center among a plurality of needle holders (10), and the second holder group may include a needle holder (10) located on the outer circumference of the center. Here, the needle (20) included in the first holder group may be inserted into the center of the target area of ​​the skin (1) to form an injection hole, and the needle (20) included in the second holder group may be inserted into the outer circumference of the target area of ​​the skin (1) to form an injection hole. Accordingly, when the actuator (30) rotates the first holder group and the second holder group in different directions, the needle (20) included in the first holder group can twist the center of the target area of ​​the skin (1) in the first direction, and the needle (20) included in the second holder group can twist the outer circumference of the target area of ​​the skin (1) in the second direction. As a result, the injection holes formed in the center of the target area of ​​the skin (1) open in the first direction, and the injection holes formed on the outer circumference of the target area of ​​the skin (1) open in the second direction, and as the center and outer circumference of the target area of ​​the skin (1) contract, moisture within the skin (1) is pushed out to the surroundings. As a result, the drug applied to or sprayed on the surface of the skin (1) can be effectively injected into the injection holes.

[0044] The actuator (30) can selectively rotate one or more of the plurality of needle holders (10). For example, the actuator (30) can rotate only one of the plurality of needle holders (10). Additionally, the actuator (30) can rotate two of the plurality of needle holders (10). In this case, the actuator (30) can rotate one of the two needle holders (10) in a first direction and rotate the other of the two needle holders (10) in a second direction. Additionally, the actuator (30) can rotate three or more of the plurality of needle holders (10). In this case, the actuator (30) can rotate the first holder group among the plurality of needle holders (10) in a first direction and rotate the second holder group in a second direction.

[0045] A plurality of needle holders (10) may be arranged in a concentric circle shape. Here, the needle holder (10) located in the center among the plurality of needle holders (10) may have a circular shape, and the remainder among the plurality of needle holders (10) may have a ring shape. Here, a gap may be formed between two adjacent needle holders (10). Thus, friction between the plurality of needle holders (10) can be prevented when the plurality of needle holders (10) rotate. Additionally, the ring-shaped needle holder (10) may be arranged to surround the circular-shaped needle holder (10).

[0046] The actuator (30) can rotate the circular needle holder (10) at the slowest speed and the ring-shaped needle holder (10) at a gradually faster speed as it moves away from the center. Accordingly, the circular needle holder (10) rotates the center of the target area of ​​the skin (1) at a slow speed to prevent damage to the skin (1), and the ring-shaped needle holder (10) rotates the outer circumference of the target area of ​​the skin (1) at a relatively fast speed to induce strong twisting. As a result, a pressure difference is formed between the center and the outer circumference of the target area of ​​the skin (1), causing moisture within the skin (1) to move as the skin (1) contracts, and as a result, the drug applied to or sprayed on the surface of the skin (1) can be effectively injected through the injection holes in the center and outer circumference of the target area of ​​the skin (1).

[0047] Hereinafter, the operation process of a drug injection device that induces twisting of the skin (1) according to one embodiment of the present invention will be described.

[0048] First, the drug may be applied to the surface of the skin (1) in advance, or the drug may be sprayed through a drug applicator (not shown).

[0049] Next, a needle (20) fixed to each of the multiple needle holders (10) is inserted into a target area of ​​the skin (1). At this time, multiple injection holes may be formed in the target area of ​​the skin (1) as the needle (20) is inserted.

[0050] Next, the actuator (30) rotates the plurality of needle holders (10). At this time, the actuator (30) can rotate the first holder group among the plurality of needle holders (10) in a first direction and rotate the second holder group in a second direction. The first holder group and the second holder group can rotate in different directions, so that one side (e.g., the center) and the other side (e.g., the outer circumference of the center) of the target area of ​​the skin (1) are twisted in opposite directions.

[0051] In this way, as the injection holes formed in the skin (1) are rotated by the plurality of needle holders (10), the injection holes are opened, and as the center and outer perimeter of the target area of ​​the skin (1) contract, a pressure difference is formed within the skin (1), causing the moisture within the skin (1) to move to the surroundings or be pushed out.

[0052] As a result, the injection hole formed in the skin (1) opens, and as the pressure environment changes due to the movement of moisture inside the skin (1), the drug applied to or sprayed on the surface of the skin (1) can be effectively injected along the injection hole. This allows the drug to rapidly penetrate into the skin (1).

[0053] FIG. 5 is a perspective view showing an example of an actuator (30) of a drug injection device that induces twisting of skin (1) according to one embodiment of the present invention.

[0054] As shown in FIG. 5, the actuator (30) may include a first drive motor (31) and a second drive motor (32).

[0055] The first drive motor (31) can selectively rotate the needle holder (10) located in the center among the plurality of needle holders (10). At this time, the drive shaft of the first drive motor (31) can be coupled to the center shaft of the corresponding needle holder (10).

[0056] The second drive motor (32) can selectively rotate the needle holder (10) located on the outer circumference of the center among the plurality of needle holders (10).

[0057] For example, the second drive motor (32) can selectively rotate a needle holder (10) located on the outer circumference of the center among a plurality of needle holders (10) through the drive roller (33), the first bevel gear (34), and the second bevel gear (35).

[0058] The drive roller (33) can be installed so as to be rotatable in place on the needle holder (10) located on the outer circumference of the center among the plurality of needle holders (10). Accordingly, when the drive roller (33) rotates in place, the needle holder (10) located on the outer circumference of the center among the plurality of needle holders (10) can be rotated.

[0059] The first bevel gear (34) is coupled to the drive roller (33), and the second bevel gear (35) can be coupled to the drive shaft of the second drive motor (32).

[0060] FIG. 6 is a cross-sectional view showing a drug injection device that induces twisting of skin (1) according to another embodiment of the present invention, and FIG. 7 is a cross-sectional view showing a negative pressure formation state of a drug injection device that induces twisting of skin (1) according to another embodiment of the present invention.

[0061] As illustrated in FIGS. 6 and 7, a drug injection device for inducing twisting of the skin (1) according to another embodiment of the present invention may further include a cylinder (40) and a pressure regulating part (50), unlike in one embodiment.

[0062] The cylinder (40) has a pressure-acting space in which a plurality of needle holders (10) are accommodated and can be in close contact with the skin (1). For example, the cylinder (40) may have its upper surface closed and only its lower surface open. Additionally, an actuator (30) may be installed in the cylinder (40).

[0063] The pressure regulating part (50) can form negative or positive pressure in the pressure action space of the cylinder (40). At this time, when negative pressure is formed in the pressure action space of the cylinder (40), the skin (1) can be pulled toward the pressure action space of the cylinder (40), and a plurality of needles (20) can be easily inserted into the skin (1). Subsequently, when the plurality of needles (20) are ejected from the skin (1), if positive pressure is formed in the pressure action space of the cylinder (40), a drug can be injected into the injection hole.

[0064] The pressure regulating part (50) may include a pressure pipe (51) connected to the pressure working space of the cylinder (40) and a regulator (52) that forms negative or positive pressure in the pressure pipe (51).

[0065] According to the present invention, a drug injection device for inducing twisting of skin (1) according to one embodiment of the present invention has the effect of efficiently inducing a drug applied to or sprayed on the surface of skin (1) along an injection hole formed in skin (1) by inducing twisting of skin (1).

[0066] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
